Palehead Blenny

Generally, individuals of Gobioclinus gobio are 2.8 to 4.0cm. The maximum length of a male palehead blenny is 6.5cm. Gobioclinus gobio has an anatomy common in Labrosomids, with a small, elongated body. The blenny has cycloid (meaning smooth to the touch) scales on the posterior body. Scales in the series 40-69 are in a lateral line, which aids in movement. Some posterior scales in the series don't have sensory tubes. On the posteroventral surface are the gill membranes, which occur continuously. The stomach cavity has a lining that is white and dotted with dark spots. Gobioclinus gobio has a broad, grey-brown head and a rounded snout. Its mouth is large and protruding, exposing the back of the upper jawbone. There are more than 2 pores on the tip of its chin. On either side of the head are two or more heavily branched cirri, which are tentacle-like structures lacking features of a traditional tentacle. The cirri are directly anterior to the origin of the dorsal fin. There may also be flaps in front of the nostrils, eyes, and nape of the fish. The palehead blenny lacks an opercular ocellus, which is a colored spot on the head resembling an eye. …

Gobioclinus gobio is a marine organism that inhabitants subtropical reefs within depths of 0–15 meters, on rocky shores with heavy vegetation, including algal mats and seagrass beds. It prefers reef habitats with coral and limestone formations, and soft substrates such as sand and gravel. Gobioclinus gobio populates the Western Atlantic coast of Latin America and around the West Indies, from Mexico to the islands of the Lesser Antilles. The blenny's distribution likely extends to the Western coast of northern South America, as well as the Antilles island chain. The blenny prefers temperatures of 26.5-28.2 degrees Celsius, with an average of 27.5 degrees Celsius.

Gobioclinus gobio's eggs are laid in benthic environments. The larvae are pelagic. Little is known about this specie's reproduction, and more research is required.
